winston-syslog hardcodes log level to 'info'

[MikeJonesSoftware]

I'm using winston-syslog to forward messages to the local syslog server, like this:

levels: winston.config.syslog.levels, format: winston.format.simple(), transports: [ new winston.transports.Syslog({ host: '127.0.0.1', port: 514, type: 'RFC5424', level: 'debug' }) ]

In my code, I use logger.info(), logger.debug(), logger.error(), etc.
In the rsyslog.conf, I expect to be able to send these logs to various files based on the severity specified when I use logger.info(), logger.error(), etc. However, it seems like winston-syslog is sending every message as info. I can replace the format property with a custom printf(), and I see that 'logLevel' is in fact correct (info, error, etc), but in the rsyslog.conf, every message that comes from winston-syslog appears to have severity of 'info'. What am I doing wrong?

I think this usage inquiry may be a better question for posting on StackOverflow.
